Becker SV 5.1050/1 15kW Side Channel Blower
The Becker SV 5.1050/1 is a high-capacity single-stage side channel blower delivering 1,080 m³/h at 50 Hz, with maximum relative vacuum of -265 mbar and maximum positive pressure of +365 mbar.
Driven by a 15kW motor, the SV 5.1050/1 is particularly suited to larger industrial installations where the process requires a substantial volume of air. Its nominal capacity exceeds 1,000 m³/h while retaining useful differential capability for both vacuum and positive-pressure operation.
The regenerative side channel operating principle provides oil-free process airflow without sliding carbon vanes. This makes the blower suitable for a broad range of industrial duties including pneumatic conveying, aeration, drying, extraction, vacuum handling and process-air systems.

High-Volume Airflow from the Becker SV 5.1050/1
The defining characteristic of the Becker SV 5.1050/1 is its 1,080 m³/h nominal capacity. This makes it suitable for industrial processes requiring substantially greater air volume than smaller side channel blower installations, while its single-stage design still provides useful differential on either the suction or discharge side.
Maximum relative vacuum reaches -265 mbar, giving the blower the ability to generate suction for extraction, handling and other vacuum processes. For pressure operation, the SV 5.1050/1 can develop up to +365 mbar relative positive pressure, supporting applications such as pneumatic conveying, aeration, drying and process-air delivery.
The balance between airflow and differential is important. A high-volume process may require hundreds of cubic metres of air per hour after allowing for the resistance created by pipework, filters, silencers and the process itself. Selecting purely from free-air capacity without considering this resistance can result in an unsuitable blower.
Inside the SV 5.1050/1, a rotating impeller transfers energy repeatedly to the air as it passes through the regenerative side channel. The progressive increase in air energy develops vacuum at the inlet and positive pressure at the discharge without requiring sliding compression components.
There are no sliding carbon vanes within the compression chamber and no lubricating oil is required in the process-air path. For appropriate applications, this provides a practical source of high-volume, oil-free industrial airflow.
Becker SV 5.1050/1 Technical Specification
This 15kW SV 5.1050/1 configuration provides a nominal capacity of 1,080 m³/h at 50 Hz, with maximum relative vacuum of -265 mbar and maximum relative positive pressure of +365 mbar.
| Model | Stage | Nominal Capacity 50 Hz |
Maximum Vacuum | Maximum Pressure | Motor Power |
| SV 5.1050/1 | Single Stage | 1,080 m³/h | -265 mbar | +365 mbar | 15kW |
The nominal capacity and maximum differential figures describe the blower’s overall performance range rather than one simultaneous duty point. Actual airflow changes as vacuum or positive pressure increases.
For this reason, an SV 5.1050/1 should be selected against the airflow required at the intended working vacuum or pressure. This is particularly important for a blower handling more than 1,000 m³/h because relatively small increases in system resistance can represent significant pressure loss across a high-flow installation.
Pipe diameter, total pipe length, bends, valves, filters, silencers and process restrictions should all be considered when assessing the complete duty.
SV 5.1050/1 Performance Characteristics
1,080 m³/h Airflow
High-volume nominal capacity for larger industrial machinery, conveying installations and process systems with substantial airflow requirements.
-265 mbar Vacuum
Useful vacuum differential combined with high air volume for extraction, handling and larger suction-side process duties.
+365 mbar Pressure
Positive-pressure capability for high-flow aeration, conveying, drying and industrial process-air applications.
Single-Stage Operation
A single regenerative compression stage prioritises substantial airflow while maintaining useful vacuum and pressure capability.
15kW Motor
The 15kW motor supports the high air throughput required from this larger SV 5.1050/1 configuration.
Oil-Free Process Air
Side channel compression requires neither carbon vanes nor lubricating oil within the air chamber.
Applications for the Becker SV 5.1050/1
The high nominal airflow of the SV 5.1050/1 makes it particularly relevant to larger installations where air volume is a major part of the process requirement. Depending on the system design, the blower can be used to create vacuum at its inlet or positive pressure at its discharge.
› High-volume pneumatic conveying
› Industrial vacuum extraction
› Printing and paper machinery
› Large packaging and production systems
› Aeration and agitation systems
› Industrial drying processes
› Vacuum handling systems
› High-volume process-air supply
For a conveying, aeration or drying system, both the required airflow and the resistance of the complete installation should be established. A nominal capacity of 1,080 m³/h does not mean the blower will deliver that same volume when operating at +365 mbar pressure or -265 mbar vacuum.
Vacuum Pumps UK can assist with blower selection where the required duty point is known and can also help assess an existing installation where the original SV 5.1050/1 needs replacing.
Replacing an Existing Becker SV 5.1050/1
Large side channel blowers are often selected as part of the original machine or process design, and their duty may be more specific than the basic model designation suggests. When replacing an SV 5.1050/1, we recommend identifying both the installed blower specification and the operating conditions it is required to reproduce.
Send Vacuum Pumps UK photographs of the complete blower, the Becker identification plate and the motor nameplate. Images showing the inlet and discharge pipework, filtration, valves and any connected silencers can also help us understand the installation.
Tell us whether the SV 5.1050/1 is being used for vacuum or positive pressure, what the blower does within the machine and whether any normal operating vacuum, pressure or airflow figures are available.
For a 1,080 m³/h blower installation, pipework and process resistance can be particularly significant. Understanding the actual system duty allows a replacement to be considered on more than model number or nominal capacity alone.
Accessories and System Protection
A blower moving 1,080 m³/h requires an installation capable of handling that air volume without creating unnecessary restriction. Correctly sized filters, pipework, silencers and protective devices can therefore have a significant influence on both blower operation and process performance.
Inlet Filtration
High-flow filtration should provide appropriate contamination protection without creating excessive suction loss as the filter loads.
Relief Protection
Vacuum or pressure relief can help prevent excessive differential if pipework becomes obstructed, filtration blocks or a system valve closes.
Silencers
Correctly sized silencers can reduce transmitted air noise while avoiding unnecessary restriction in a high-volume installation.
Pipework & Connections
Adequate pipe diameter, suitable bends and correctly selected fittings help preserve available airflow and reduce avoidable system losses.
SV 5.1050/1 Service, Repair and Spare Parts
Although regenerative side channel compression avoids the rubbing vanes associated with some other vacuum technologies, an industrial blower still contains mechanical components requiring attention throughout its working life. Bearings, the motor and associated components can deteriorate with operating hours and service conditions.
Changes in noise, vibration or temperature can indicate a developing mechanical issue. A loss of machine performance should also prompt checks outside the blower itself, particularly on a high-flow system where a blocked filter, restricted pipe run, leakage or process change can substantially alter the operating point.
Vacuum Pumps UK can inspect Becker side channel blowers in our workshop, investigate reported faults and advise whether service, repair or replacement is the appropriate route.
